%'msgbox_uvmat': associated with GUI msgbox_uvmat.fig to display message boxes, for error, warning or input calls
% msgbox_uvmat(title,display)
%
% OUTPUT:
% answer  (text string)= 'yes', 'No', 'cancel', or the text string introduced as input
%
%INPUT:
% title: string indicating the type of message box:
%          title= 'INPUT_TXT','CONFIMATION' ,'ERROR', 'WARNING', 'INPUT_Y-N', default = 'INPUT_TXT' (the title is displayed in the upper bar of the fig). 
%          if title='INPUT_TXT', input data is asked in an edit box
%          if title='CONFIMATION'', 'ERROR', 'WARNING', the figure remains  opened until a button 'OK' is pressed
%          if title='INPUT_Y-N', an answer Yes/No is requested
% display, displayed text
% default_answer: default answer in the edit box (only used with title='INPUT_TXT')
